Defect

On rear two-axle drive vehicles, two separate deficiencies exist in the front drive axle differential (inter-differential case): (1) Instructions issued under a prior recall were inadequate, leaving wear on the spline joint between the inter-differential case and the propeller shaft coupling. This wear allows the castle nut to loosen. (2) The thread strength at the coupling mounting is insufficient. When the propeller shaft installation angle is large and input loads on the threads are high, the threads may fracture. Continued operation under either condition can cause the coupling to separate from the inter-differential case and, in the worst case, result in propeller shaft detachment and loss of mobility. (Note: This recall supersedes the recall filed July 26, 2000, under Notification No. 649. The corrective instructions issued under that recall were inadequate; this filing revises those instructions and expands the corrective action and affected population.)

Corrective action

On all vehicles, replace the inter-differential case with a corrected part. Because corrected parts require time to procure, an interim measure applies in the meantime: inspect the inter-differential case installation condition. Replace any unit found to be abnormal with a corrected part immediately. Units found to be normal will receive the corrected part at a later date.

状況

後2軸駆動車の前側駆動軸差動機(インターデフケース)において、 ①リコールによる改善措置の指示が不適切なため、推進軸接手との嵌合いスプライン部に  摩耗が残ったままのものがあり、キャッスルナットにゆるみが生じるものがある。 ②接手取付け部ねじ強度が不十分なため、推進軸取付け角度が大きくねじ部への入力が大  きい場合、当該ねじ部が折損するものがある。そのため、そのままの状態で使用を続け  ると接手が抜け出し、最悪の場合、推進軸が脱落して走行不能となるおそれがある。   (備考) 本届出は平成12年7月26日付け「届出番号649」のリコール届出に対し、対策措置指示 が不適切であったため指示内容を見直し、さらに対策内容、対象範囲を見直し、再度対策 を行うものである。

改善措置

全車両、インターデフケースを対策品と交換する 。 なお、対策品の供給に時間を要するため、当面の暫定措置として、インターデフケースの取 り付け状態を点検し、異常のあるものは対策品と交換する。異常のないものは後日対策品 と交換する。
